. WINDOW-REGULATOR.

Specification of Letters Patent.

Application filed October 14, 1914. Serial No. 866,572.

To all whom it may concern:

Be it known that I, JOHN E. MARSDEN, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Window-Regulator,

of which the following is a specification.

My inventioh resides in means for regulating the position of a window, andmore particularly a vehicle wmdow, as 111 the door of a carriage, automobile or the like; And my invention resides further in means for locking the window in any of its positions; and also in means for rendering the window rain-tight or weather-proof.

For an illustration of one of the forms my invention may take reference is tobe had to the accompanying drawings, inwhich:

Figure 1 is a vertical sectional view, some parts in elevation, through the window and its frame or support. Fig. 2.is a vertical elevational view, parts in section looking at the side of theparts shown in Fig. 1. Fig. 3' is a vertical cross sectional view, some parts in elevation, on a larger scale, of a partof a window and its operating means. Fig. 4 is a sectional view through a chain sprocket and associated parts. Fig. 5 is a fragmentary sectional view, on a larger scale, taken on the line X'-X of Fig. 2. Fig. 6 is a sectional view, similar to that shown in Fig. 3, showing the weather-strip and window in closed position.

Referring to the drawings, l represents a window casing or frame, such as an automobile door in which the window pane 2 is slidable vertically in the lateral guide slots 3 in which, as indicated in Fig. 5, may be suitable lining material such as cloth or metal.

At its lower end the pane 2 may be grooved, as at 5, to receive indentations 6 in the metal clamp 7. The clamp. 7 is secured to the lateral projection 8, upon the vertically disposed strip 9 attached to the sprocket chain 10 which engages the upper sprocket wheel 11 and the lower sprocket wheel 12.

The handle or knob 13 has atubular projection 14 secured by screw 15'to the rotary shaft 16 which extends through the escutcheon plate 17 and the member 18 forming part of the door or frame. The member 14 is adapted to move in the bore '19 in the hollow boss 20 on the escutcheon plate 17. And in the bore 19 is disposed the helical spring 21 opposing movement from right to left, as

viewed in Fig. 3, of the handle 13 and attached parts. On the inside of the member 18 is secured a plate 22by screws 23 extending through the member 18 and the plate 17. An eyelet 24 through which the shaft 16 extendsengages the stationary plate 22 with one of its flanges and with its other engages the sprocket wheel 11 holding the. same against the plate 22 with respect to which the wheel 11 is rotatable. A ball-bearing 25 is'provided for the sprocket 11. The plate 22 is circular inform and has the circumferential slots 26 disposed between corresponding teeth, the slots being equally spaced circumferentially and being of any desired number. Secured upon the end of the shaft 16 is a spider 27, here shown as having four arms, each with an inturned end 28 adapted to normally engage in the slots 26. These inturned ends pass through slots 29 in the sprocket 11.

The lower sprocket 12 is rotatable upon the shaft 30 secured by a squared end 31 to the plate 32 on the end of an arm 33 pivoted at 34 and having the rearward extension 35 with a the adjustable screw 37 threaded in the stationary bracket 38, adjustment of the screw 37 adjusting the position of arm 33 and thereby determining the distance between the centers of the sprockets 11 and 12 and therefore adjusting the tension on the chain 10. j

A casing 39 is rotatable upon the shaft 30 with the sprocket 12 because of the connection between them afforded by the screw 40. Within the casing 39 is housed the spiral spring 41 whose inner end is attached at 42 to the shaft 30 and whose outer end is connected to the casing 39. The spring 41 is so disposed that it is wound up when the window pane 2 is lowered and accordingly assists in raising the window 2, or acts as a counterbalance therefor.

A sill or member 43 extends transversely of the door or frame and has secured to its inner face the inwardly curved or tapered guide plate 44 reaching to within a short distance of the pane 2. A vertically disposed tubular member 45 is supported upon the member 43 and within the member 45 is disposed a vertically movable rod or plunger 46 whose upper end is secured between the plates 47 and 48 which between their upper 6 g6S clamp or hold the rubber or other Patented Oct. 5, 1915.

weather-strip 49 the plunger 46 and member 45 serving to guide the weather-strip 49 in its vertical movement. Beneath the weatherstrip 49 and between the plates 47 and 48 is disposed the end of a spring 50 secured at 51 to the framing, the spring 50 tending to press the weather-strip downwardly by pressing downwardly upon the member 46. Secured to the chain 10, as by being secured to the plate 9, is the bracket or projection 51 adapted to engage the undersides to the plates 47 and 48.

The operation is as follows: \Vith the window fullyclosed, as shown in Figs. 1, 2 and 6, the weather-strip 49 is wedged firmly between the strip 44 and thewindow pane 2 forming a rain-tight or weather-proof joint. To lower the window, the operator presses inwardly from right to left, as viewed in Figs. 1 and 3, upon the handle 13, in opposition to spring 21, thereby lifting the ends 28of the spider 27 from the slots 26 in the member 22, thus unlocking the sprocket 11. While retaining the pressure upon the handle 13, the handle 13 is rotated, causing rotation of the sprocket 11 and rotation of sprocket 12 through the chain 10 which latter pulls through the plate 9 and clamp 7 downwardly upon the window 2 lowering the same. When the window has been lowered to any suitable point the inward pressure upon handle 13 is released, whereupon the spring 21 forces the handle and shaft 16 outwardly carrying the ends 28 of the spider 27 into the nearest notches 26, whereupon parts are again locked in position, thus looking the window 2 in its adjusted position. This movement of the chain 10 has caused the spring 41 to be wound up. And as the one side of the chain 10 descended, the projection 51 was withdrawn from beneath the Weather-strip plates 47 'and 48 and the spring 50 has carried the weather-strip 49 downwardly to the position indicated in Fig. 3. When desiring to close the window,

the handle 13 is again pressed inwardly to unlock the parts and then rotated in opposite direction whereupon the member 9 will push upwardly on member 7 and thus raise the window 2 the upward movement being assisted by the spring 41. When the window 2 has almost reached its closed position the member 51 engages the edgesof the parts 47 and 48 and raises the weather-strip which is deflected against the window 2 by the guide '44 and as the upward movement is completed the weather-strip 49 is partly raised by the member 51 and partly dragged or wedged by the window 2 until the closed position indicated in Figs. 1, 2 and 6 is again reached.

"While I have described the sprocket chain as part of the driving mechanism it will be understod that any other form of belt may be used, or that a pinion driven by the handle 13 may mesh with a rack attached to the window, in which case the member 51, operating the weather-strip, would be attached to such other belt or. to the rack. i What I claim is:

l. The combination with a window frame and a window membermovable therein, of means for moving said member, a weatherstrip supported on said frame, and means movable with said first named means for automatically moving said weather-strip against said member.
